Title: Pressure die casting apparatus
IPC: B22D18/08
Filed: 1976-10-26
Abstract: The apparatus is intended, on the one hand, to guarantee a freely accessible space under the frame supporting the casting mould and, on the other hand, to allow continuous operation. For this purpose, an intermediate crucible (1) is arranged in such a way next to the casting mould (4) that the maximum level of metal in the intermediate crucible (1) is lower than that in a siphon pipe (3) connecting the intermediate crucible (1) to the casting mould (4). Arranged in the intermediate crucible (1), above the maximum level of metal, is a bell-shaped shut-off element (6) which shuts off the supply (7) from the main crucible (8). The upper bend (2), the siphon pipe (3) and the free space both in the intermediate crucible (1) and in the main crucible (8) are connected to one another and to a tank (15) for compressed inert gas by control elements (9, 10, 11, 12, 13, 14). On the other hand, a chamber (16) which contains the casting mould (4) is connected to a compressed-air tank (19) which, for its part, is connected by means of control elements (20) to the gas tank.   The apparatus is intended for the casting of metals under low pressure or back pressure. <IMAGE>

Abstract: 1473149 Cutting apparatus M GRANGER 14 Oct 1974 [12 Oct 1973 12 Feb 1974] 44516/74 Heading B4B A device for cutting sheet materials, e.g. paper comprises two elongate co-operating members 1, 6 between which the material is adapted to be fed, one member being mountable on a wall mounting or pedestal and being provided with stationary cutting means 5 and the other cooperating member having at least one cutting means 20 movable relative to the stationary cutting means and straddling the stationary cutting means along its length. The stationary cutting means may comprise a heat-treated wire, e.g. piano wire 5 secured under tension to a surface of U-section support member 1; the wire is tensioned by a screw-adjustment device (18, 19), Fig. 11 (not shown). Alternatively, the cutting means may be formed as a ridge integral with the member 1. The material, e.g. textiles, plastics, wadding, may be supported on a roll which is rotatable on bearings 12 secured to arms 3, the latter being adjustable along the member 1 and locked in position by knurled nuts (11), Fig. 5 (not shown). The member 1 may be secured to wall-backets 2 adapted to be screwed to a vertical surface by screws 2c. The movable cutting member may be in the form of a pair of ball-races 20, Fig. 8, provided with mating chamfered ends to form a V-groove which straddles the wire 5; alternatively the V- groove may be formed on a roller (21), Fig. 9 (not shown) or the cutting member may be in the form of a disc 22 running alongside the wire 5. The ball-races (or roller) are freely rotatable on a carrier 23 provided with three rollers 24 adapted to run on a guide rail 6, the carrier being moved by a handle 25. The rail is connected to the support member 1 by threaded bolts 13 provided with nuts 15 so that the distance between the rail 6 and support member 1 may be adjusted. In the modification shown in Fig. 12, a pair of cutting rollers 27 are mounted on a T-shaped lever 26 which is pivotally connected to the carrier 23 such that by movement of the handle 28, extra pressure can be applied to the cutting rollers. In the modification shown in Fig. 16, a pair of bearings 35, 36 are mounted on a C-shaped spring-steel carrier and adapted to co-operate with a curved edge formed on a bar 31 adapted to be attached to the edge of a working surface T; the carrier is provided with rollers 37 which engage the bottom edge of the bar, the resilience of the carrier causing the bearings to firmly engage the bar. The curved edge may be formed with serrations or ridges in order to improve the grip during cutting. In a further modification, Figs. 18 to 20 (not shown), a C-shaped carrier (41) having bearings (43, 44) is arranged to run in a U-section support member 38 which may rest on a horizontal support surface or provided with plates (46), Fig. 21 (not shown), for attachment to a plate 47 which may be secured to a wall; a support (48) for a roll of material may also be secured to the plate. The amount of material to be pulled from the roll may be measured by a spring-loaded tape measure (29, 30), Fig. 14 (not shown).

Abstract: 987,384. Control of A.C. motors. MANNHEIMER MASCHINENFABRIK MOHR & FEDERHOFF A.G. Nov. 20, 1963, No. 45799/63. Drawings to Specification. Heading H2J. The holding and closing lines of an excavating bucket are each driven by an induction motor. Before lowering operation is commenced, the stator windings are connected in parallel to a single phase of a three phase supply, the rotor windings being interconnected through a damping resistor. The brake of the closing motor is released to allow its rotor to align with the rotor of the holding motor. During the lowering operation the holding motor is overdriven by the load, the motors operating at the same speeds due to the interconnection between their rotor windings. This enables the bucket to be lowered in the open condition over. its entire range of movement. The speed is limited by a further resistor in the rotor circuits. The stator windings may be connected in series.

Preferably the solutions contain 8 or 11% by weight of nitrogen and 24 or 33% of phosphorus respectively. Solutions of the above composition are prepared by heating wet process phosphoric acid containing Al and Fe to remove water and volatile impurities, neutralizing with ammonia and diluting with water.  Preferably the wet process acid of P2O5 content between 45 and 55 weight per cent is heated to between 120-400 DEG  C. to form an equilibrated mixture of orthophosphoric and acyclic polyphosphoric acid having a calculated mole ratio of water to P2O5 of 2.1 to 3.5, and then reacted with water and ammonia at 30-100 DEG  C., or anhydrous ammonia at 150 DEG to 225 DEG  C., and then water can be added to obtain a final phosphate concentration of between 45 and 50% by weight.  The heated wet process acid may either be adjusted to a P2O5 content of 20-30% and the acid reacted with anhydrous ammonia or at P2O5 content of 35-55% when the acid is reacted immediately with 20-30% aqueous ammonia. The wet process acid may be heated so that the minimum content of polyphosphoric acid is at least as great as given by the equation <FORM:0997932/C1/1> where P2O5 poly = gram moles of P2O5 as polyphosphoric acid per 100 grams of acid; P2O5 ortho = gram moles of P2O5 orthophosphoric acid per 100 grams of acid; M = total atoms of non-volatile metal impurities per 100 grams of said phosphoric acid; a = average valence of non-volatile metal impurities = <FORM:0997932/C1/2> wherein the atomic symbols represent the gram atoms of their respective metal per 100 grams of said phosphoric acid and K is no greater than 0.5 x 10-2.
